If you are curious, here are some of the numbers that you can call but you will not be charged for the call.
This article is based on https://www.antonwidawan.com/ The first one is 111. This is the first number that you can call if you want to talk with the service centre of Indosat. This number is totally free to call so that you will not be charged even just a penny. Unfortunately, there is one thing that you need to know. This number can only be dialed if you are using Matrix as one of the products from Indosat. If you are using some others such as Mentari or IM3, you will not be able to dial the number.
The next one is 222. Actually, this one is not the real human operator. By dialing 222 from your current Indosat SIM card, you will be redirected to the machine that will answer your questions. Because of that reason, you will not be charged at all. For your consideration, if you are looking for some information related with your current SIM card, calling this number is not a problem. However, if you want to deliver a complaint, calling this number might be useless since you will be answered by a machine. Therefore, you need to choose which number that you can call best based on your need.
